About this map

Knudsen Ranch and several family-named reservoirs define the landscape of this Lassen County high-country region in the early 21st century. The terrain is a network of arid flats and volcanic hills, where water management is central to the land's utility, as seen at McClelland Reservoir, Myers Reservoir, and Packwood Reservoir. The drainage patterns of Willow Cr and the various forks of Juniper Cr carve through the plateaus, creating distinct landforms such as Windmill Flat and Packwood Flat.

Forestry and ranching infrastructure are evident in the naming of roads like Anderson Ranch Rd and Snider Lake Rd. Notable elevations including Letterbox Hill and Manzanita Hill provide landmarks above the deep incisions of Letterbox Canyon and Preston Canyon. The survey also documents localized water sources such as Twin Lakes and the secluded Snider Lake, essential for livestock and local wildlife.
